GB5310ikhodi ejwayelekile yezinga likazwelonke lase-China elithi "Seamless Steel Pipes forAma-boilers anengcindezi ephezulu", ecacisa izidingo zobuchwepheshe zamapayipi ensimbi angenamthungo kumabhoyela anengcindezi ephezulu namapayipi esitimu. Izinga le-GB5310 lihlanganisa amamaki ensimbi ahlukahlukene ukuze kuhlangatshezwane nezidingo ezihlukene zohlelo lokusebenza. Okulandelayo kungamanye amabanga avamile nezimboni zawo zokufaka isicelo:

20G: I-20G ingelinye lamabanga asetshenziswa kakhulu ku-GB5310, enezingxenye eziyinhloko zekhabhoni, i-manganese ne-silicon. Inezakhiwo ezinhle ezibanzi zemishini kanye nezakhiwo zokushisela, futhi isetshenziselwa ikakhulukazi ukwenza izingxenye ezibalulekile njengezindonga ezipholiswe ngamanzi, ama-superheaters, i-economizers kanye nezigubhu kumabhoyela eziteshi zamandla kagesi.

15CrMoG: Le nsimbi iqukethe i-chromium ne-molybdenum, futhi inamandla aphezulu okushisa nokumelana ne-oxidation. Amapayipi ensimbi angenamthungo we-15CrMoG avame ukusetshenziselwa ukwenza amapayipi esitimu esishisa kakhulu kanye nawomfutho ophezulu, izihloko namapayipi, njll., futhi asetshenziswa kakhulu ezimbonini ze-petrochemical kanye nezimboni zamandla.

12Cr1MoVG: Iqukethe i-chromium ephezulu, i-molybdenum ne-elementi ye-vanadium, nokusebenza okuhle kakhulu kwezinga lokushisa eliphezulu nokuzinza kwesikhathi eside. Amapayipi ensimbi angenamthungo aleli banga avame ukusetshenziswa kuma-boilers anezinga lokushisa eliphezulu kanye ne-high-pressure kanye nemishini yamandla enyukliya, ikakhulukazi ama-heat exchangers, amapayipi omusi, njll.

Lawa mabanga ahlukene amapayipi ensimbi engenamthungo asetshenziswa kakhulu ekwenziweni kwezingxenye ezibalulekile endaweni enezinga lokushisa eliphezulu kanye nengcindezi ephezulu njengamandla, i-petrochemical, namandla enuzi ngenxa yokwakheka kwawo kwamakhemikhali okuyingqayizivele kanye nezakhiwo zemishini. Ngokukhetha izinga elifanele lensimbi, ukuphepha nokuzinza kwemishini ngaphansi kwezimo zokusebenza ezinzima kungaqinisekiswa, futhi impilo yesevisi inganwetshwa.
